KRAS G12V

This suggests a potential mechanism explaining the increased sensitivity of CRC cells harboring a KRAS-activated pathway to acetate. These findings contribute to a clearer understanding of how KRAS regulate BAX function, a relevant aspect in tumor progression.

The Agena iPlex HS Lung Panel on the MassARRAY System is highly tolerant of poor quantity and quality DNA, recovering and delivering accurate results on samples that would otherwise fail NGS-based analysis.

Recently, an emergency approval from the US-FDA has been issued for KRASG12C inhibitors (sotorasib and adagrasib) for metastatic lung cancer treatment. Moreover, because KRASG12D and KRASG12V are more common than KRASG12C, focus must be placed on the therapeutic strategies for this type of patient, along with sustained efforts in research on these targets. In the present review, we try to focus on various strategies to overcome rapid resistance through the use of combinational treatments to improve the activity of KRASG12C inhibitors.

KRAS-mut represents a genotypically distinct group of ECs. Overlap exists with genomic predictors (TMB-high, MSI-high) of immunotherapy response, suggesting a possible biomarker-driven combination option with immunotherapy. Clinical trials to evaluate these strategies should be developed.

Notably, patients harboring the G12C variant responded favorably to sotorasib medication. These results underscore the importance of mutational profiling and targeted therapeutic approaches in managing NSCLC, particularly highlighting the promising efficacy of sotorasib in G12C-mutated cases.

The TCRs were derived from healthy donors or patients with pancreatic cancer who had received a vaccine against mutant KRAS. The most promising TCRs warrant testing in patients with KRAS G12V-positive cancers.

LLS30 effectively disrupts the Gal-1/Ras interaction, resulting in significant anti-tumor and anti-metastatic effects in MPNST models. These findings indicated that targeting Gal-1 with LLS30 offers a promising therapeutic approach for treating MPNSTs and may also be applicable to other malignancies where Gal-1 and Ras are key oncogenic drivers.

Throughout treatment, KRAS ctDNA is detectable by ddPCR in patients with localized PDAC treated with NAC. Detection of mutant KRAS G12V after resection was associated with reduced OS.

In contrast, patients with detected KRAS G12R in the tissue survived nearly twice as long as other patients in the aggregate (286 days, 95% CI: 70-602 vs. 162 days, 95% CI: 122-600, p = 0.0374) or patients with other KRAS mutations (286 days, 95% CI: 70-602 vs. 137 days, 95% CI: 107-600, p = 0.0257). Differentiation of specific KRAS mutations in EUS-FNB and ctDNA (above all, the crucial G12D and G12R) is feasible in routine management of PDAC patients and imperative for assessment of prognosis.

ARMS-HRMA is a rapid and cost-effective method for detecting KRAS mutations in PDAC patients, offering the potential for stratifying prognosis and guiding treatment decisions. The presence of G12D and G12C mutations in both tumor and plasma is associated with a poorer prognosis.

Increased TMB was observed in cases of KRAS and BRAF mutation combined with APC single mutation; furthermore, the expression of TMB in G12V was the highest, and G12D presented the lowest TMB in single KRAS-mutant subtypes or the combination with APC mutations. The TMB driven by KRAS co-mutations may have the potential to be used as a key biomarker for prediction of treatment outcomes of immune checkpoint inhibitors (ICIs) in patients with CRC, especially with APC co-mutation.

We investigated cell viability, drug synergies, pERK suppression and cytokine, chemokine or growth factor alterations following treatment with 5-Fluorouracil (5-FU) or ONC212 plus MRTX1133 in 6 human CRC and 4 human pancreatic cancer cell lines. Our studies reveal preclinical activity of MRTX1133 alone or synergies when combined with 5-FU or ONC212 against mCRC and pancreatic cancer cells regardless of KRAS G12D mutation. The results suggest that KRAS G12V and KRAS G13D should be further considered in clinical trials including combination therapies involving MRTX1133 and 5-FU or ONC212.
